Depth of Page Location

Generally, the deeper a page’s location in the site’s structure, the less frequently it will be indexed (and thus Google’s index of that page’s content will be less up to date).

“Depth” of location refers to how deep the page is in the site, for example, if a page is found directly from a Home page link, it is not deep. If a Search Engine spider (or website user) has to drill down through four pages before it finds a link to the page, then that page is a “deep page”.

The use of javascript or server-redirect links. Search Engines cannot follow javascript pop-ups or server redirect links (except 301 server redirects). If you are linking to a page, then choose standard HTML links wherever the CMS allows you to.
